Busenbach–Ittersbach railway

The Busenbach–Ittersbach railway is a line in the northern Black Forest in the German state of Baden-Württemberg. The mostly single-track and continuously electrified line branches in Waldbronn-Busenbach from the Alb Valley Railway (German: Albtalbahn)—with which it is closely linked operationally and historically—and runs as a branch line to Ittersbach. The Albtal-Verkehrs-Gesellschaft (Alb Valley Transport Company, AVG) is responsible for the railway infrastructure and is the only company operating on the 14.4 kilometre-long line. Originally the Busenbach–Ittersbach railway was operated together with the Ittersbach to Pforzheim line, which later became the Pforzheim Light Railway (Pforzheimer Kleinbahn). The whole line from Busenbach to Pforzheim was initially built to 1,000 mm (3 ft 3+3⁄8 in) metre gauge, later the section from Busenbach to Ittersbach was rebuilt to 1,435 mm (4 ft 8+1⁄2 in) standard gauge and the Pforzheim Light Railway was closed. The line has been operated as part of line S 11 of the Karlsruhe Stadtbahn since 1994.
